## Description

The Crypto.Random.atfork function in PyCrypto before 2.6.1 does not
properly reseed the pseudo-random number generator (PRNG) before allowing a
child process to access it, which makes it easier for context-dependent
attackers to obtain sensitive information by leveraging a race condition in
which a child process is created and accesses the PRNG within the same
rate-limit period as another process.
